Cylinder Valves
V600 Series

Ultra High Purity Diaphragm Cylinder Valve is developed for the semiconductor industry. It is designed for use with ultra high purity gas cylinders to prevent gas leakage and achieve the low leakage rates demanded by high purity gas users.

Features

• Manual and actuated versions are available based on a common body design
• Suitable for most special gases including variants for oxygen and highly corrosive gases such as chlorine and hydrogen chloride
• Final assembly and testing is carried out under class 10 clean room conditions
• Designed for the low leakage rates demanded by high purity gas users
• Non tied-diaphragm construction; the diaphragms act directly on the seat to close the valve, which minimizes dead space and wetted area
• Mechanically supported and retained valve seat to minimize deformation under load and seat lift under reverse flow conditions
• The diaphragm isolates the operating mechanism from the process fluids
• The one-piece, non-welded construction improves durability
• To prevent the shedding of particulate contamination, there are no sliding, rotating or rubbing components in the flow path
• Inlet and outlet port configurations are available to suit all known industry standards. The same valve family can be used for all fluids in all market areas
• For transportation the actuator can be locked closed to prevent shock induced leakage
• The outlet port is sealed and protected by a cap retained by a chain
• The valve mechanism incorporates secondary sealing for enhanced safety
